题目内容
The last Thursday of November, _______ as a day of thanksgiving in western countries, is an important festival.
| A．observing | B．being observed | C．to be observed | D．observed |
D
解析试题分析：考察非谓语动词。本题中句中主语the last Thursday of November与动词observe(庆祝)，构成被动关系，故使用过去分词短语observed as a day of thanksgiving in western countries作为定语来修饰the last Thursday of November。句意：十一月的最后一个星期四在西方国家被作为感恩节来庆祝，这是一个重要的节日。B项中是现在分词的被动形式，表示正在进行。C项不定式表示未来，均不符合。故D正确。
考点：考察非谓语动词
